If not, find out what query is crashing (see postmaster log), and if you can get a stack trace out of one of the core files, that'd be pretty helpful too. https://wiki.postgresql.org/wiki/Generating_a_stack_trace_of_a_PostgreSQL_backend We might need to ask for a self-contained test case, if the stack trace doesn't make it clear what's failing. regards, tom lane
